Left-Hand Lug Nuts for Alloy Wheels

[JHertzman@domain.elided]

In AD7-1460 Randy King asked about suitable lug-nuts for his Panasports on 
his '69 GT Veloce (which has both right-hand and left-hand threads, as all 
pre-1972 Alfas did) and three days later in AD7-1468 Milt Simon asked a 
similar question - "I cannot find 12mm x 1.50 mag-type lug nuts, the chrome 
acorn-type that go about 3/4" into the wheel.  The standard ones for the 
later Spiders are EASY, but the left-hand style are impossible. Any advice?  
To change the studs wont help because i believe they screw in."

Working backwards from the easy part, the studs DO NOT screw in but are a 
press fit. The front hubs 105.41.21.400.00 are the same on 1750s and 2000s, 
so there should be no difficulty using the later studs and any nuts which 
will work with alloys on later Spiders, if one is willing to forgo the nicety 
of left-handed threads.

If one is a purist (or wishes to be one-up on the bastardizers at the 
concours) there MAY (perhaps, not certain) be a solution in the OEM lug nuts 
used on the optional alloy wheels on the 1750. The optional alloy wheels for 
the 1750 (Fergat 5-1/2J x 14) may or may not have the same wheel-to-nut 
interface as the Panasport (etc) - don't know, don't have either, let alone 
both. However, the 1750 used the same bolts (105.41.21.417.01 left hand, 
105.41.21.418.01 right hand) for both the steel wheels and the alloys, but 
used different nuts: 105.32.28.100.01 right-hand thread for cast wheels, 
105.32.28.101.01 left-hand thread for cast wheels. The 105.32 prefix 
identifies these nuts as having been used originally on the GTA, if that 
helps. The local dealer might not have them on hand, but they should be 
obtainable; and if not, (or if they don't work for other reasons) the late 
studs and nuts should be a practical and readily available solution.
